Gold Hydrogen Confirms Natural Hydrogen and Helium in Ramsay 3 Well in Australia

Overview

Gold Hydrogen Limited (ASX: GHY) has confirmed the presence of natural hydrogen and helium in its Ramsay 3 well on South Australia’s Yorke Peninsula, reinforcing the area’s potential as a new gas province. This confirmation adds momentum to the company’s 2025 drilling program and supports the strategic interest recently shown by several major industrial partners.

Ramsay 3 well results

The Ramsay 3 well is located about 2.3 kilometres from the earlier Ramsay 1 and Ramsay 2 wells, tying the new discovery into an existing zone of natural hydrogen and helium occurrences. Elevated levels of natural hydrogen were identified in the Parara Limestone using SLB’s DQ1000 gas detector, while helium was detected at multiple depths within the Kulpara Dolomite formation.

These measurements indicate that natural hydrogen and helium are present not just at a single point but across a broader geological system within the Ramsay Project area. Several gas samples from the well have been collected and sent for independent laboratory testing, with analytical results expected in the near term.

Indications of system continuity

Data from Ramsay 3, combined with earlier drilling at Ramsay 1 and Ramsay 2, suggests continuity of natural hydrogen and helium within key stratigraphic units such as the Parara Limestone and Kulpara Dolomite. This continuity is important because it points to a potentially extensive subsurface gas system rather than isolated pockets.

The company interprets these findings as evidence that the Ramsay Project could evolve into a significant new gas province focused on naturally occurring hydrogen and helium. Follow‑up testing and appraisal work will be necessary to better define the distribution, concentrations, and commercial recoverability of these gases.

Strategic and commercial context

Gold Hydrogen’s progress at Ramsay 3 follows recent strategic investments by Toyota Motor Corporation, Mitsubishi Gas Chemical, and ENEOS Xplora, which view natural hydrogen and helium as important future energy and industrial gases. These partnerships underscore the potential market relevance of a successful development at the Ramsay Project.

Natural hydrogen is attracting interest as a low‑carbon energy source, while helium remains a critical input for technologies such as medical imaging, electronics manufacturing, and scientific research. If Ramsay can deliver commercially viable volumes of both gases, it may position Gold Hydrogen as a notable supplier in emerging and established markets.

Management commentary

Gold Hydrogen’s Managing Director, Neil McDonald, highlighted that confirming elevated levels of natural hydrogen and helium at Ramsay 3 is an important milestone for the project. He noted that the new results support the extension of the natural hydrogen system previously identified in the Parara Limestone and indicate helium system continuity in the Kulpara Dolomite section.

“Confirmation of elevated levels of natural hydrogen and helium at Ramsay 3 is very exciting. This helps demonstrate the potential for the extension of the natural hydrogen system previously identified by the company in the Parara Limestone. Further, the confirmation of helium gas shows in the Kulpara Dolomite section is also indicative of system continuity. We look forward to receiving the laboratory results and continuing our testing program.”

Next steps and outlook

Gold Hydrogen plans additional testing at Ramsay 3, including detailed analysis of collected gas samples and further well performance assessments. More extensive testing is expected in the coming months to clarify flow characteristics, gas composition, and the broader resource potential.

The company views Ramsay 3 as another step toward proving a natural hydrogen and helium field on the Yorke Peninsula and informing decisions on future drilling locations. Outcomes from this work will guide appraisal and potential development plans as Gold Hydrogen seeks to advance a new gas province in South Australia.

Author’s summary

Gold Hydrogen’s Ramsay 3 findings strengthen evidence of a continuous natural hydrogen and helium system on South Australia’s Yorke Peninsula, supporting the project’s promise as a future gas hub.
